NESTED LOOP

                 When a loop is used inside another loop then it is called a nested loop. All the three loops (for, while
                 and do-while) provided by JavaScript can be used as nested loop. Syntax to use nested loop is:

                 Outer loop
                 {
                     Inner loop
                     {
                               //Statements to be executed in the inner loop
                     }
                               //Statements to be executed in the outer loop
                 }
